Title: Improvements in or relating to mops
IPC: A47L1/06
Filed: 1932-06-16
Abstract: 379,266. Mops. SENDLER, T., 7, Konigstrasse, Stettin, Germany. June 16, 1932, No. 17007. Convention date, Nov. 19, 1931. [Class 19.] A mop for floors, walls, and the like, provided with a divided head and squeezing means, is characterized in that the handle is hinged to the divided head so that the mop can reach underneath furniture and be applied flat to walls. The mop head parts also are capable of being swung towards one another by a pulling device on the handle for squeezing out the mop. Parts a, b, Fig. 1, of the mop have coverings d and are pivoted at p to two side plates e. A forked handle c is pivoted at n to the side plates. A hook k locks the handle. Attached to each part a, b is a toothed segment r secured by a bolt s. To one segment r is hinged by a link m a rod h movable in the mop handle i. Movement of the rod h rocks the segments r so as to squeeze the parts d together. The rod h, Fig. 4, has a transverse pin t working in slots w in the handle i. A recess v serves to lock the pin t in its lowest position corresponding with the position shown in Fig. 1. A sleeve x surrounds the handle and holes through which the pin t passes are of such a length that the pin can move transversely under the action of a spring f to engage the slot v. To hold the rod h in position when the mop is in use, the rod has a projection y which engages with a hole in the hollow handle i as soon as the rod h under the action of the spring f is pressed into its lowermost position in the slot v. If the mop parts are to be squeezed, then the pin t is forced out of the slots v by outside projections (not shown) into the slots w. The sleeve x can now move upwardly and the mop parts be forced together to squeeze out the water.

Abstract: 1501823 Purification of percarboxylic acids BAYER AG and DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 28 April 1976 [30 April 1975] 17175/76 Heading C2C Percarboxylic acid solutions in organic solvents, which are capable of forming azeotropes minimum-boiling with water, having a b.pt. lower than that of the percarboxylic acid, are simultaneously freed of water and H 2 O 2  by distilling the solution so that at least 1À5 times the amount of organic solvent which is required for the removal of the water content of the solution as an azeotrope is vaporized and withdrawn as the top product which is separated into an aqueous phase containing H 2 O 2  and a phase which contains the organic solvent, and returning the latter as reflux to the distillation, a substantially anhydrous and H 2 O 2 -free organic solution of the percarboxylic being obtained as the sump product from the distillation. Preferably 1À5-40 times the required amount of solvent is removed in the distillation which may be conducted under a pressure of 100-400 mm.Hg. The process is advantageously used to purify benzene solutions of 15-25 wt. per cent percarboxylic acid, e.g. perpropionic acid, with 0À5-5 wt. per cent of both water and H 2 O 2 .

Filed: 1916-12-07
Abstract: 110,975. Birmingham Railway Carriage & Wagon Co., Holloway, H. H., and Hill, E. O. Dec. 7, 1916. Buffers.-Relates to buffers of the type in which an outer cylindrical casing and a hollow sliding plunger enclose a compressed helical spring, and the plunger is provided with meane for retaining it in the casing against the pressure of the spring. The retaining-bolt C is provided at its inner end with a T-head 2 and at the other end with a nut D arranged in a central boss 1 in the plunger-head, and relative rotation of the bolt and plunger A is prevented by a cotter 10 passing through the bolt and engaging longitudinal slots 11, 12 in tongues 8, 9 extending inwardly from the boss 1. The casing B is provided with a boss 5 having an internal flange 4 formed with an elon. gated slot 3, so that the plunger may be connected to the casing by first passing the T-head 2 through the slot 3 as indicated in Fig. 3, rotating the plunger and bolt through 90 degrees so as to engage the T-head behind the flange 4, and then screwing up the nut D so as to compress the spring E and also to cause the tongues 8, 9 to enter the slot 3 as shown in Fig. 1 and thus lock the plunger against rotation. The inward movement of the plunger and the compression of the spring are limited by the engagement of the cotter 10 with the ends of the slots 11, 12. The nut D is formed with a suitable head 15 so that the only tool necessary to effect the connexion is a box spanner, and substantial longitudinal movement. of the nut relative to the plunger is prevented by a grub-screw 13 engaging a groove 14 in the nut. Entire removal of the nut from the bolt during the backward or disconnecting movement is prevented by a cross-pin 20 formed on a reduced extension 16 of the bolt and adapted to engage a flange 18 at the inner end of a recess 19 formed in the nut. A self-locking washer 22 of the spring split-ring type is arranged between the nut D and a shoulder 21 on the boss 1 so as to prevent rotation of the bolt C under vibrations. When the nut D is rotated in assembling the parts, the washer 22 is compressed and the grub-screw 13 passes to the outer edge of the groove 14 as shown in Fig. 1; when the nut is turned for disconnecting the parts, the washer expands and the screw 13 passes to the inner edge of the groove 14 as shown in Fig. 3.

Title: Magnetic memory apparatus
IPC: H04M1/272
Filed: 1956-06-11
Abstract: 823,075. Electric digital-data-storage apparatus. AUTOMATIC ELECTRIC LABORATORIES Inc. June 11, 1956 [July 19, 1955], No. 17974/56. Class 106 (1). A digital data storage device includes a storage medium comprising a non-magnetic member having a plurality of isolated magnetic elements embedded therein, relatively movable write-in means selectively energizable to induce magnetizations of a particular polarity in selected ones of said elements, and means for causing relative movement between the storage medium and read-out means. As shown, a non- magnetic circular disc 70 contains a number of magnetic elements 75 arranged in radial rows a1, a2, &c., and concentric circles W, X, Y, Z, all the elements being normally magnetized in one axial direction so as to repel permanent magnet armatures 93. The disc is rotatably mounted on a shaft 17 and is rotated in a counter-clockwise direction, as shown in Fig. 3, by an electromagnetically driven pawl-andratchet stepping mechanism, the rotary position being indicated by indicia 86. Four write-in heads 76W, 77X, 78Y, 79Z are in the form of electromagnets having polepieces 80 to 83 disposed on one side of the disc, four read-out devices being provided on the opposite side of the disc, the read-out devices comprising permanent magnet armatures 93 and normally open contacts 96 arranged on contact spring sets 87 to 90. An item of information is written into the store in a four-element binary code, the four magnetic elements 75 corresponding to one item being arranged one in each circle of elements in a spiral group such as on the spiral 100, Fig. 6. When the disc is in its initial rotary position the spirally-arranged write-in heads are selectively energized to change the magnetization polarity of the four elements associated therewith in accordance with the coded representation of the item of information to be stored. The disc is then stepped on by one and the next item of information is stored. In this way in a complete revolution of the disc a total number of items of information equal to the number of radial rows of elements 75 may be stored. The energizing circuit for the electromagnets 76W to 79Z are now opened and on a subsequent complete revolution of the disc, the information stored therein may be read out. When the first spiral group of elements 75 appears under the similarly arranged read-out armatures 93, the armatures associated with the reversed elements only will be attracted thereto to close contacts 96. On subsequent advancement of the disc by one position by the stepping mechanism, a new group of elements 75 will be brought into association with the armatures 93. In this way all the information stored in the disc may be read out. A group of elements which have been read may be cleared when advanced into association with the electromagnets 76W to 79Z by passing currents of opposite polarity to the writing currents through the electromagnets. Specification 805,599, [Group XXXIX], is referred to.
